The clinical supervision ratio of students to instructors must be coordinated to support patient safety by taking into consideration: the student’s knowledge and ability; the physical status of the patient; the complexity of the anesthetic and/or surgical procedure; and the experience of the instructor (ref. 2004 Standards – Standard V, Criterion E13 and PDS Standard F.9). Clinical oversight of graduate students in the clinical area must not exceed two graduate students to one CRNA, or two graduate students to one anesthesiologist (if no CRNA is involved).
